Plans. 


They  show  the  location  of  the  work  and  its  general  character. 
Dining  the  progress  of  the  work,  such  working  plans  will  be 
furnished  from  time  to  time  by  the  Engineer  as  he  may  deem 
necessary. 

Test  pits  and  borings  have  been  made  to  ascertain  the 
position  of  the  bedrock  at  the  site  of  the  work  and  the  charac- 
ter of  the  materials  overlying  it:  should  the  character,  location 
and  extent  of  the  various  materials  be  found  to  differ  from  what 
is  indicated  by  the  test  pits  and  borings,  the  Contractor  shall 
have  no  claim  on  that  account,  and  it  is  expressly  understood 
that  the  Company  does  not  warrant  the  indications  of  the  tests, 
as  noted  on  the  plans,  to  be  correct. 

The  dam  is  to  be  erected  across  the  Ogden  River  Valley,  at 
a  point  about  eight  hundred  feet  below  the  mouth  of  Wheeler 
Canyon.  It  will  be  about  three  hundred  and  forty  feet  long, 
sixty  feet  high  above  the  river  bed,  with  thirty  or  forty  feet  of 
foundations.  Its  foundations  will  be  carried  down  to  solid 
rock  and  into  solid  rock  to  such  a  depth  as  may  be  determined 
by  the  Engineer- 
On  the  right  or  north  bank  of  the  river,  a  spillway  or 
overflow  weir  of  masonry  will  be  built,  approximately  at  right 
angles  to  the  axis  of  the  main  dam  and  about  one  hundred  and 
fifty  feet  in  length:  Its  crest  will  be  eight  feet  below  the  top 
of  the  main  dam.  There  will  be  a  channel  connected  with  it, 
following  the  contour  of  the  side  hill,  by  means  of  which  the 
water  flowing  over  the  spillway  will  be  conducted  to  the  bed 
of  the  river  below.  This  channel  will,  as  far  as  possible,  be 
excavated  iu  the  bedrock. 

Bids  are  requested  on  three  distinct  Plans,  called  in  these 
specifications  and  in  the  drawings  accompanying  them  Plans 
A,  B  and  C  respectively. 


General 


PLAN  A. 

ALL  MASONRY  DAM. 

This  plan  provides  for  a  masonry  dam  of   the   usual  form 
and    construction,     as    shown    on     Sheets    I.    II    and    Till. 


19 

The  entire  dam  and  spillway  are  to  be  built  throughout  of  uu-. 
coursed,  broken  range  rubble  masonry,  built  of  quarry  stone 
of  regular  sizes  and  shapes,  laid  with  full  beds  and  joints  in 
Portland  cement  mortar. 

The  faces  of  the  dam  will  be  built  of  the  same  class  of 
masonry  as  the  central  portion,  but  the  best  stones  and  those 
of  the  most  regular  form  must  be  selected  for  the  face  and  the 
joints  must  be  closer. 

Both  faces  must  be  carefully  pointed  with  Portland  cement 
mortar. 

A  stone  coping,  fifteen  inches  thick  and  three  feet  wide, 
shall  be  laid  in  cement  mortar  on  either  side  of  the  roadway 
for  the  entire  length  of  the  dam  and  shall  support  the  iron 
hand  railing. 

Cut  dimension  stone  will  be  used  only  for  these  copings 
on  the  top  of  the  dam  and  for  the  crest  of  the  overflow  weir,  or 
in  such  other  places  as  may  be  designated  by  the  Engineer. 


PLAN   B. 

DAM  WITH  CONCRETE  PIEKS  AND  ARCHES, 
As  Shown  ou  Sheets  III,  IV.  V  and  VIII. 

This  form  of  dam  is  to  be  built  of  concrete  masonry,  but 
the  up-stream  face  will  be  enclosed  with  a  thin  steel  plate  cov- 
ering, bolted  to  the  concrete  to  prevent  abrasion  and  the  perco- 
lation of  water. 

There  will  be  in  all  six  separate  piers  and  two  abutments, 
joined  together  by  circular  concrete  arches,  both  on  the  up- 
stream face  and  on  the  top  of  the  piers. 

The  piers  will  be  sixteen  feet  in  thickness  aud  the  clear 
spans  ;5'2  feet.  The  extrados  of  the  arches  which  support  the 
water  pressure  is  to  be  cylindrical,  the  external  radius  being 
everywhere  equal  to  25  feet.  The  thickness  of  the  arches  shall 
be  (>  feet  for  the  upper  (50  feet  of  the  dam  (that  is,  down  to  el- 
evation 4795).  It  shall  be  7  feet  for  the  next  20  feet  in  height 
(that  is.  to  elevation  4775  ).  and  8  feet  from  the  last  given  ele- 
vation to  the  bedrock. 


20 

The  interior  surfaces  of  the  different  sections  will  have 
radii  of  19,  18  and  17  feet  respectively. 

The  arches  and  piers  shall  be  built  of  concrete,  mixed  in 
accordance  with  the  requirements  hereinafter  specified  for  con- 
crete and  for  cement.  The  exact  proportions  of  ingredients 
used  will  vary  in  the  different  parts.  In  general,  the  propor- 
tions will  be  one  part  of  cement,  two  parts  of  sand,  and  four 
parts  of  broken  stone  for  all  arches  and  for  that  part  of  the 
piers  which  is  within  two  feet  of  the  exterior  surface;  also  for 
all  concrete  deposited  under  water.  In  the  rest  of  the  work, 
the  proportion  will  be  one  part  of  cement,  to  three  parts  of 
sand  and  five  parts  of  broken  stone. 

The  concrete  shall  be  carefully  rammed  in  forms  or  molds 
of  proper  shape.  For  the  upper  faces  of  the  arches  and  piers, 
the  steel  plates,  properly  braced,  shall  serve  as  molds. 

The  roadway  arches  shall  be  semi-circular,  the  radius  of 
the  intrados  being  10  feet  and  the  thickness  of  the  arch  rings 
3  feet.  They  shall  be  16  feet  in  length  at  the  springing  and 
shall  be  extended  to  make  a  proper  joint  with  the  arches  of  the 
up-stream  face  and  shall  be  absolutely  continuous  with  the  lat- 
ter. The  spandrel  spaces  above  the  roadway  arches  and  the 
piers  shall  be  filled  with  concrete  to  the  level  of  the  roadvvav. 
A  stone  coping  15  inches  thick  and  8  feet  wide  shall  be  laid 
in  cement  mortar  on  either  side  of  the  roadway  for  the  entire 
length  of  the  dam  and  shall  support  the  iron  hand  railing. 

The  steel  plate  facing  shall  be  everywhere  j  of  an  inch  in 
thickness.     It  shall  cover  the  entire  up-stream  face  of  the  dam. 
Steel  Plates  fitting  closely  to  the  concrete  of  the  piers  and  arches,  to  which 
it  will  be  bolted  by  short  bolts,  as  indicated  in  the  plans. 

The  steel  plates  in  front  of  the  arches  shall  be  rolled  to 
form  a  segment  of  a  circle.  The  radius  will  be  25  feet,  the 
versed  sine  8  feet,  9  inches,  and  the  actual  length  of  each 
segment,  measured  on  the  arc,  43  feet,  2  inches. 

The  flat  plates  forming  the  facing  of  the  piers  shall  be  10i 
feet  long,  making  a  lap  joint  with  the  curved  plates.  All  con- 
nections between  the  plates  shall  be  riveted  lap  splices  for  both 
the  horizontal  and  vertical  joints. 


21 

There  shall  be  at  every  joint  a  single  row  of  three-quarter 
inch  rivets  spaced  three  inches  apart.  They  shall  be  carefully 
driven,  the  heads  being  closely  pressed  down  with  special 
reference  to  the  exclusion  of  water. 

The  edges  of  the  plates  on  the  upper  surface  shall  be 
calked,  preferably  by  suitable  machinery,  so  that  the  entire 
sheeting  shall  be  strictly  water-tight  under  the  greatest 
hydraulic  pressure  prevailing.  The  edges  of  all  plates  must 
be,  in  the  opinion  of  the  Engineer,  sufficiently  smooth  to  allow 
of  sufficient  calking.  Whenever  this  is  not  the  case,  they  must 
be  planed  off  to  a  smooth  surface. 

The  plates  covering  the  arched  surface  shall  be  as  large 
as  practicable  so  as  to  have  the  least  number  of  joints.  A 
vertical  joint  shall  be  made  on  the  line  that  the  arch  springs 
from  the  pier,  the  flat  plate  being  bent  to  the  proper  angle  to 
make  a  lap  joint  with  the  curved  plate. 

The  holes  for  the  rivets  shall  be  laid  out  with  templets 
and  shall  be  punched  carefully  so  as  to  make  an  accurate  fit, 
but  they  need  not  be  reamed. 

The  quality  of  steel  for  the  plates  and  rivets  is  given  here- 
after under  the  heading  "Requirements  for  Steel  Plates  and 
Rivets.'' 

The  surface  of  the  plate  facing  which  is  to  come  in  con- 
tact with  concrete  shall  be  thoroughly  cleaned  before  the  con- 
crete is  deposited,  but  shall  not  be  painted.  The  outer  surface 
must  be  cleaned  and  then  coated  with  two  coats  of  Paraffine 
P.  &  B.  paint. 

All  paint  of  improper  composition  or  badly  applied,  or 
applied  upon  surfaces  which  have  not  been  properly  cleaned, 
or  where  the  surface  has  been  abraded,  shall  be  thoroughly- 
scraped  off  and  such  surfaces  repainted,  as  may  be  directed  by 
the  Engineer.  Painting  shall  be  begun  and  continued  as  fast 
as  the  riveting  and  calking  will  permit. 

The  method  of  procedure  in   building    this   form    of  dam 
f    w*'^  ('el)(J11(l   «1)011   circumstances,   an(l    particularly    upon    the 
Procedure,    amount  of  ground   water  encountered.       The    Contractor    will 
ordinarily  be  allowed  to  adopt  those  methods  which    will   con- 
duce   to    the    greatest  economy   consistent    with    good    work. 
Some  suggestions,  are,  however,    hereinafter  given   under  the 


22 


beading  "Plan  C."  for  his  benefit  in  making  a  proposal,  which 
appear  to  indicate  the  most  practicable  methods  of 'putting  in 
that  portion  of  the  dam  which  will  be  below  the  level  of  the 
ground  water. 

PLAN    C. 

DAM  WITH  COXCKETE  PIEI;S  AND  A  STEEL  PLATE  FACING. 
As  Shown  on  Sheets  VI,  VII  and  VIII. 

This  form  of  dam  will  be  built  entirely  of  concrete  mason- 
ry and  curved  steel  plates  joined  by  rivets.  The  abutments 
at  both  ends  of  the  dam  will  be  built  of  concrete.  Between  the 
abutments  and  connecting  with  them,  the  upper  face  of  the  dam 
will  consist  of  steel  plates  supported  by  concrete  piers,  piers 
being  11  feet  (>  inches  thick  and  clear  span  between  the  piers 
'23  feet.  The  piers  will  be  connected  together  at  the  top  l>y 
concrete  arches  supporting  part  of  the  roadway.  The  lower  "2") 
feet  of  the  steel  plate  face  will  be  imbedded  in  a  wall  of  con- 
crete 15  feet  thick  and  'l~i  feet  high.  The  concrete  in  the  abut 
ments,  toe-wall,  arches,  and  two  feet  of  thickness  of  piers  along 
the  steel  plates,  shall  be  composed  of  Portland  cement  con- 
crete, in  the  proportions  of  one  of  cement,  two  of  sand,  and 
four  of  broken  stone.  These  proportions  shall  alto  be  used 
wherever  concrete  is  deposited  under  water,  and  within  two 
feet  of  anv  contact  with  iron  work.  Other  portions  of  the 
concrete  will  be  mixed  in  the  proportion  of  one,  three  and  five, 
unless  otherwise  directed.  The  bedrock  shall  be  thoroughly 
cleaned  and  all  cracks  shall  be  filled  with  grout  immediately- 
preceding  the  depositing  of  the  concrete. 

The  steel  plate  face  is  designed  for  sheets  8  feet  10 
inches  wide  (including  lap)  but  sheets  may  be  made  of 
any  width  to  suit  the  manufacturer.  Length  of  sheets 
for  the  span  plate  is  *2Ti  feet  and  for  the  pier  plate  18  feet  (> 
inches.  Assuming  twelve  plates  in  the  vertical  height,  the 
thickuess  of  plates  numbering  from  the  top  will  be  as  follows: 

Plates  Nos.  1,  2,  3,  4,  5  and  (>,  $  inch:  Nos.  7  and  8.  7- It) 
inch:  Nos.  9,  10,  11  and  12,  A  inch. 

All  horizontal  splices  will  be  lap  joints  with  a  single  row 
of  rivets,  3-inch  pitch.  Vertical  joints  of  plates  Nos.  1.  '1.  '•'> 
and  4  will  be  lap  joints,  two  rows  of  rivets.  34  inches  pitch  in 


23 

each  row.  Plate  No.  5  same  as  above,  but  the  pitch  shall  be  3 
inches  in  each  row.  All  rivets  in  plates  Nos.  1  to  5  inclusive 
shall  be  steel,  |  of  an  inch  in  diameter.  All  rivets  m  plates 
Nos  (i  to  12  inclusive  will  be  steel,  £  of  an  inch  in  diameter. 
Vertical  joints  in  plate  No.  (5  will  be  lap  splice,  two  rows  of 
rivets,  3 1  inch  pitch  in  each  row.  In  plate  No.  7  lap  joints, 
two  rows  of  rivets,  2^  inch  pitch  in  each  row.  All  vertical 
joints  in  plates  Nos.  8  to  12  inclusive  will  be  made  with  double 
butt  straps  10  by  §  inches  in  section,  with  two  rows  of  rivets 
on  each  side  of  the  joint.  31  inch  pitch  in  each  row. 

All  joints  must  be  calked  as  far  as  possible  by  machine,  so 
as  to  be  absolutely  tight  under  the  maximum  hydraulic  pres- 
sure, and  edges  of  plates  and  butt  straps  must  be  planed  to  a 
bevel  to  facilitate  calking.  Edges  of  plates  not  calked  need 
not  be  planed. 

No  coating  must  be  put  on  the  plates  until  after  calking 
and  riveting  is  done,  and  every  precaution  must  be  taken  to 
keep  the  plates  free  from  rust  and  dirt.  All  plates  to  be  in 
contact  with  concrete  must  be  thoroughly  cleaned  before  the 
concrete  is  deposited.  Oilier  surfaces  must  be  thoroughly 
cleaned  and  then  coated  with  two  coats  of  Paraffine  P.  &  B. 
paint.  All  paint  of  improper  composition  or  badly  applied,  or 
applied  upon  surfaces  which  have  not  been  properly  cleaned, 
or  where  the  surfaces  have  been  abraded,  shall  be  thoroughly 
scraped  off  and  such  surfaces  repainted,  as  may  be  directed  by 
the  Engineer.  Painting  shall  be  commenced  and  prosecuted 
as  fast  as  the  riveting  and  calking  will  permit. 

The  Engineer  may  decide,  in  lieu  of  paint,  to  put  a  ce- 
ment coating  to  a  height  of  25  feet  above  the  top  of  the  toe- 
wall. 

The  method  of  procedure  in  building  the  dam  will  de- 
pend upon  ability  to  control  subterranean  water. 

It  is  proposed  first  that  an  excavation  shall  be  made  of  the 
whole  site  of  the  darn  to  as  low  elevation  as  it  can  be  carried 
without  the  use  of  sheet  piling.  After  this  is  done,  a  sheet 
pile  cofferdam  shall  be  sunk  to  bedrock  for  one  of  the  piers  in 
the  middle  of  the  river,  to  be  designated  by  the  Engineer. 
This  shall  be  pumped  out  and  the  bedrock  thoroughly  exam- 
ined, and  such  excavation  made  into  it  as  may  be  directed. 


•24 

The  steel  plate  for  tlie  back  of  this  pier  shall  be  put  in 
place  and  concrete  deposited  in  the  excavation  so  made  and 
carried  to  such  a  height  as  the  Engineer  may  direct. 

If,  upon  the  investigation  of  this  pier  site,  such  a  course 
is  deemed  practicable,  the  steel  face  imbedded  in  the  toe-wall 
shall  be  put  in  place  for  its  entire  length  and  brought  above 
the  surface  of  the  water.  The  steel  plate  for  the  entire  width 
of  the  dam  shall  then  be  put  in  place  and  thereafter  kept  above 
the  top  of  the  concrete. 

The  construction  of  the   remaining    piers   can  then  follow. 

If  the  above  course  is  not  deemed  practicable,  it  is  the  in- 
tention to  put  in  a  cofferdam  for  each  pier  separately,  and  to 
carry  them  up  to  the  elevation  of  the  top  of  the  toe-wall,  im- 
bedding the.steel  plate  in  concrete  in  each  pier,  but  leaving 
the  end  for  riveting  clear  by  approved  form  of  wooden  protec- 
tion. From  the  top  of  the  toe-wall,  the  steel  plate  shall  be 
carried  up  continuously,  riveting  of  each  course  being  done  be- 
fore concrete  is  deposited  against  it.  Subsequently,  cofferdam 
excavation  shall  be  made  between  the  piers  for  placing  the 
steel  plate  and  portion  of  the  toe- wall  in  each  span.  If  practi- 
cable, concrete  will  be  laid  in  dry  excavation,  but  it  may  be 
decided  to  lay  it  under  water.  The  Contractor  will  ordinarily 
be  allowed  to  adopt  those  methods  which  will  conduce  to  the 
greatest  economy  consistent  with  good  work,  the  above  sugges- 
tions being  made  for  his  benefit  in  making  Proposal. 

The  toe-wall  being  designed  to  exclude  the  water  below 
the  steel  plate,  if  crevices  are  discovered  which  would  defeat 
this,  they  shall  be  followed  out  above  the  dam,  as  directed, 
and  stopped  by  excavation  and  concreting,  as  may  be  directed. 

Work  The  different  parts  of  the  work  to  be  done  under  the  con- 

To  Be  Done  t,.act  may  be  divided  as  follows: 

(a)  Making  necessary  excavations    in  both  earth  and  rock    for 
stripping  the  site  of  the  dam  and  preparing  the  foundations. 

(b)  Cleaning  off  the  bottom   of  the  foundations,    filling    up 
crevices  and  irregularities  in  the  bottom,   in   accordance    with 
the  instructions  of  the  Engineer. 

(c)  Doing  all  pumping  and  other  temporary    work    necessary 
to  keep  the  excavation  clear  of  water,   and   taking   care    of  the 


water  in  the  river  according  to  such  methods  and  by  such  ap- 
pliances as  may  be  approved  by  the  Engineer. 

(d)  Constructing  all  the  masonry  and  steel  work   in   the  dam 
and  waste  weir. 

(e)  Refilling  those  portions  of   the   excavations  not   occupied 
with  masonry  with  earth  excavated,  or  such  other   material  as 
may  be  selected  for  that  purpose. 

If)  Doing  all  necessary  rock  and  earth  excavation  and  masonry 

and  concrete  work  necessary  for  the  construction  of  a  spillway 
and  overflow  channel  for  carrying  the  surplus  water  to  the  bed 
of  the  river. 

(S)  I"  general,  doing  all  work  necessary  for  the    entire   con- 

struction of  the  dam  and  spillway,  and  delivering  the  whole 
structure  to  the  Company  in  a  completed  condition,  with  the 
masonry  all  pointed,  with  the  dam  ready  to  be  put  into  service, 
in  accordance  with  the  plans  and  these  specifications. 

It  is,  moreover,  agreed  and  understood,  that  the  prices  for 
the  different  classes  of  work,  as  hereinafter  stated  (Clause  Q) 
shall  constitute  full  payment  for  the  work  covered  by  the

Method,    of  prosecuting  the  same  will  be   left  to   the  discretion    of   the 

Contractor,  with  whom    the    responsibility    of   such   order  and 


method  shall  rest;  provided,  however,  that  the  Engineer  shall 
at  all  times  have  the  right  to  prescribe  and  control  such  order 
and  methods  with  a  view  to  safety,  rapidity  and  economy  in  the 
execution  of  the  work. 


PROTECTIVE  WORKS. 

The  Contractor  shall  be  responsible  for  all  damage  done  to 
the  work  bv  water,  whether  from  negligence  or  any  other 
cause,  during  the  whole  period  of  time  covered  by  his  contract. 
He  shall  do  all  work  needed  to  protect  his  work  from  water; 
he  shall  erect  all  temporary  dams,  cofferdams,  sheet  piling, 
flumes,  and  other  devices,  and  shall  do  all  necessary  draining 
and  pumping.  Such  damage  as  may  be  caused  is  to  be  re- 
paired by  him.  without  cost  to  the  Company. 

The  cost  of  furnishing  the  necessary  appliances,  of  work- 
ing them,  and  of  pumping  and  draining,  shall  be  included  in 
the  prices  bid  for  the  various  kinds  of  work. 


EXCAVATION.

(Clause  Q,  items  d  and  e). 


Earth 


27 

The  prices  stipulated  for  earth  excavation  shall  cover  the 
work  of  removing,  handling,  and  transporting  to  spoil  banks 
and  for  refilling  of  all  earth,  loam,  clay,  sand,  gravel,  quick- 
sand, mud,  muck,  hardpan,  cemented  material,  stones,  boulders 

Excavation      „ 

ot  less  than  one  cubic  yard  in  volume,  wood,  and  of  anv   other 

objects  or  substances  found  below  the   existing   surface  of  the 
ground,  except  rock,  as  specified  below. 

The  excavation  shall  be  made  in  accordance  with  the  lines 
and  grades  established  by  the  Engineer,  and  the  prices  paid 
for  earth  excavation  shall  include  all  sheeting,  bracing,  and 
shoring  required  for  supporting  the  sides  of  the  excavation. 
They  shall  also  include  all  pumping,  ditching,  and  draining, 
and  the  disposal  of  the  excavated  material  in  sjxjil  banks,  which 
shall  be  located  at  such  points  as  may  be  designated  by  the 
Engineer,  and  also  for  refilling  such  portions  of  the  excava- 
tion as  are  not  occupied  by  the  masonry. 

The  excavation  shall  be  made  with  sloping  sides  or  in 
vertical  trenches,  as  may  be  deemed  best  by  the  Engineer  at 
different  stages  of  the  work.  The  depth  at  which  the  sloping 
excavations  are  to  be  abandoned  and  the  vertical  trenches  are 
to  be  begun  will  depend  on  the  character  of  the  materials 
encountered,  and  cannot  be  fixed  in  advance.  In  any  case, 
the  shores  and  bracing  must  be  so  disposed  as  to  enable  a 
careful  inspection  of  the  rock  bottom  to  be  made,  and  so  as 
to  interfere  as  little  as  possible  with  the  laying  of  the 
masonry. 

The  work  to  be  done  under  this  head  consists  of  all  the 
earth  work  necessary  for  refilling  that  part  of  the  foundation 
pits  not  occupied  by  the  stone  work  of  the  dam  and  waste 
weir.  The  material  necessary  for  refilling  shall  be  selected 
material,  taken  from  dumps  formed  during  the  process  of 
excavation.  The  Engineer  shall  decide  upon  the  quality  and 
Refilling.  character  of  the  earth  to  be  used  at  various  places  for  re- 
filling, and  it  must  be  selected  and  placwl  in  accordance  with 
his  orders.  Care  must  be  taken  in  refilling  to  fill  all  portions 
of  the  foundation,  so  that  no  vacant  spaces  may  remain.  The 
price  for  refilling  shall  be  included  in  the  price  paid  for 
earth  excavation. 


28 

Kock  excavation  is    to   include   the   excavation  of  all  solid 
rock.  that.  is.  of  all  material  which,  in    the   opinion  .  of  the  En- 
Rock       giiieer,  cannot    be    removed    by  picking,  and  boulders  of  one 
Excavation  culji(.  yard  or  more  in  size.     It  shall  be  measured  in  excavation 
to  the    lines    determined    by  the  Engineer  and  estimated  for 
payment  in  accordance  with  these  lines  only. 

In  preparing  the  foundations,  the  rock  shall  be  excavated 
on  the  bottom  and  sides  of  the  valley  to  such  depths  and 
widths  as  may  be  necessary  to  secure  a  proper  bonding  and 
connection  of  the  masonry  to  the  rock,  in  accordance  with  the 
directions  of  the  Engineer.  It  may  be  roughly  shaped  in  the 
form  of  trenches  or  steps,  if  required  by  the  Engineer. 

All  excavation  of   rock    for   the    foundation  of  the  dam  on 
Must   Not    the  bottom  and  sides  of   the  valley   is   to    be    made  with  black 
Use  High    pl)Wder.  and  not  with  high  explosives.      Black    powder  may  be 
ordered  used  exclusively  for  rock   excavation  where   the  Engi- 
neer may  so  designate. 

Preparing  After  excnvating  all  materials  from  the  surface  of  the  bed- 

Founda-     rock,  the  bedrock  shall   be   excavated  to  the  depth  of  one  foot, 
tions.        O[.  more)  if   necessary,    to   obtain    rock  of  such  character  as  will 
afford  a  good,  firm  foundation. 

Across  the  dam  site  and  parallel  to  its  front  face,  trenches 
shall  be  e-cavated  to  the  depth  of  two  feet  or  more,  and  the  toe 
of  the  dam  shall  be  placed  not  less  than  two  feet  below  the 
natural  surface  of  the  bedrock.  These  trenches  need  not  be 
perfectly  straight,  but  shall  be  excavated  so  as  to  form  an  ir- 
regular surface  throughout  the  area  of  the  foundation,  to  re- 
ceive the  bottom  of  the  foundation  walls  and  to  resist  the  slid- 
ing of  the  whole  structure  upon  the  natural  bedrock  surface. 

After  the  natural  rock  surface  is  exposed  and  all  loose 
rock  is  removed,  by  picking  or  otherwise,  from  the  surface,  the 
whole  area  of  the  surface  is  to  be  scrubbed  clean  with  wire 
brooms  and  washed  with  streams  from  a  hose,  to  disclose  any 
seams  or  fissures  that  may  exist.  If  ordered  by  the  Engineer, 
such  seams  or  fissures,  if  found,  shall  be  followed  out  by  exca- 
vation until  they  entirely  disappear,  and  said  excavation  shall 
be  filled  with  concrete  made  of  one  part  Portland  cement  and 
two  parts  sand  and  four  parts  broken  stone:  said  concrete  to  be 


29 

thoroughly  compacted  by  ramming  until  the  water  flushes  to 
the  surface,  and  allowed  to  set  thoroughly  before  walking  over 
or  any  work  is  done  upon  it. 

After  the  natu  ral  surface  of  the  rock  is  prepared  to  receive 
the  foundation,  grout  shall  be  thoroughly  worked  into  all  seams 
and  fissures  just  before  depositing  the  mortar,  and  not  enough 
in  advance  of  the  mortar  to  enable  it  to  set  independently. 

In  such  excavations  of  the  natural  rock  as  above  described 
are  to  be  laid  the  foundations  of  the  dam,  such  foundations  to 
be  well  bonded  and  laid  in  Portland  cement  mortar,  as  herein 
specified  against  the  shoulder  of  the  natural  rock. 


MASONRY. 

All  masonry,  except  where  otherwise  specified,  shall  be 
laid  in  Portland  cement  mortar,  and  shall  be  built  of  the  forms 
and  dimensions  shown  on  the  plans,  or  as  directed  by  the  En- 

<nneer  from  time  to  time,  and  the  system  of  bonding  ordered 
To  be  Laid  n

No  masonry  is   to   be   built   between   the  15th  day  of  De- 
cember  and   the    loth    day  of  March,  nor  in  freezing  weather, 
except  by  permission  of  the  Engineer.      All  fresh  masonry,  if

Masonry. 


Rubble 
Masonry. 


All  masonry  shall  be  built  according  to  tlie  plans  and  in- 
structions furnished  by  the  Engineer,  and  will  be  estimated 
and  paid  for  by  the  cubic  yard  of  twenty-seven  cubic  feet,  com- 
puting only  the  actual  volume  thereof.  No  constructive  or 
conventional  measurement  will  be  allowed,  any  local  rule  or 
custom  to  the  contrary  notwithstanding.  The  Contractor  will 
be  required  to  furnish  the  materials  for  and  to  construct  all 
masonry  in  all  places  where  masonry  may  be  required  by  the 
Engineer  for  the  proper  completion  of  the  work  contemplated. 

Masonry  will  be  classified  as  follows:  Dimension  stone 
masonry,  rubble  masonry  and  concrete  masonry. 

•f  V  * 

Dimension  stone  masonry  will  be  used  only,  if  ordered 
by  the  Engineer,  for  the  parapet  walls  and  copings  of  the 
main  dam  and  for  the  steps  or  crest  of  the  overflow  weir. 

It  shall  be  built  of  selected  sandstone,  limestone  or 
granite,  of  uniform  appearance  and  acceptable  to  the  Engineer. 
The  stones  shall  be  cut  to  exact  dimensions,  and  all  angles  and 
arrises  shall  be  true,  well  defined  and  sharp.  All  beds,  builds 
and  joints  are  to  be  dressed,  for  the  full  deptli  of  the  stone,  to 
surfaces  allowing  of  '£  inch  joints  at  most.  The  face  of  the 
stones  shall  be  rock  faced,  or  rough  pointed,  or  hammer 
dressed,  at  the  option  of  the  Engineer.  The  exposed  surfaces 
of  the  cut  stones  are  generally  to  be  prepared  with  rock  face. 
The  inside  surfaces  are  generally  to  be  rough  pointed.  The 
tops  of  the  copings,  bridge  seats,  etc.,  will  generally  be  ham- 
mer dressed. 

Rubble  masonry  will  be  used  for  all  parls  of  the  all 
masonry  dam  (Plan  A),  except  where  dimension  stone  is  dis- 
tinctly specified,  or  in  the  foundation,  where  concrete  may  be 
used  at  the  option  of  the  Engineer. 

Rubble  masonry  shall  be  laid  without  any  attempt  at  reg- 
ular courses.  The  stones  shall  be  hard,  sound,  durable,  of  good 
size  and  form,  and  free  from  dust.  dirt,  or  other  improper  sub- 
stance, and  from  loose  seams  or  other  defects.  They  must  have 
roughly  rectangular  forms  and  all  irregular  projections  and 
feather  edges  must  be  hammered  off  before  the  stones  are  set. 
The  beds  must  be  good  for  materials  of  this  class  and  must 
present  such  even  surfaces  that,  when  lowering  a  stone  on  the 
surface  prepared  to  receive  it,  there  may  be  no  doubt  that  the 
mortar  will  fill  all  spaces.  Care  must  be  taken  to  select  the 


31 

largest  and  best  stones  for  the  face  work  and  to  use  the  smaller 
ones  for  filling  the  span -s  and  interstices.  Each  stone  shall  be 
laid  on  its  natural  bed  in  a  thick,  swimming  bed  of  mortar,  and 
thoroughly  settled  down  in  its  place.  Stones  must  be  laid  so 
as  to  break  joints  with  each  other,  both  horizontally  and  verti- 
cally, so  as  to  insure  the  greatest  bond  and  strength. 

After  all  spaces  and  interstices  are  completely  filled  witli 
mortar,  fragments  of  stones,  or  spalls,  shall  be  hammered  into 
them.  Care  must  be  taken  to  prevent  the  formation  of  large 
pockets  of  mortar  alone,  and  to  place  stones  of  appropriate 
size  and  shape  in  all  spaces  of  considerable  magnitude  on 
exposed  faces  of  walls. 

The  quality  of  the  beds  is  to  regulate,  to  a  large  extent, 
the  size  of  the  stones  used,  as  the  difficulty  of  forming  a  good 
bed  joint  increases  with  the  size  of  the  stones. 

Various  sizes  must  be  used  and  regular  coursing  must  be 
avoided,  in  order  to  obtain  vertical  as  well  as  horizontal  bond- 
ing. 

The  sizes  of  the  stones  used  will  vary  also  with  the  char- 
acter of  the  quarries,  but,   especially   in    the   places  where   the 
Sizes.  thickness  of  the  masonry  is  great,  a  considerable  proportion  of 

lanje  stones  is  to  be  used. 

O 

Generally  the  largest  stones  are  not  to  measure  more  than 
twenty  cubic  feet,  and  they  are  to  be  used  in  the  proportion  of 
about  twenty-five  per  cent  of  the  whole,  and  they  must  be 
omitted  partially  or  entirely  if  their  beds  are  not  satisfactory. 
It  is  expected  that  one-quarter  of  the  stones  used  will  be  of 
such  size  that  two  men  can  handle  them.  The  balance  to  be 
composed  of  intermediate  sizes. 

If,  in  the  opinion  of  the  Engineer,  the  size  and  character 
of  the  stones  shall  admit  of  it.  the  joints  (except  the  beds),  in- 
stead of  being  rilled  with  mortar  may.  at  his  request  or  on  his 
approval,  be  filled  with  concrete  made  as  hereinafter  specified, 
with  the  exception  that  the  component  materials  shall  be  mixed 
in  the  proportion  of  one  part  of  cement  to  three  parts  of  small 
stone  or  gravel,  of  such  size  as  the  Engineer  shall  direct,  and 
thoroughly  rammed,  care  being  taken  to  use  a  moderate  amount 
of  water  only  which  must  be  brought  to  the  surface  by  ramming, 
such  filling  of  joints  with  concrete  to  leave  no  vacancies  and  to

be  thoroughly  made.  If  concrete  is  so  used,  the  spaces  left  be- 
tween the  stones  should  not  be  less  thnu  six  inches,  in  order 
that  proper  ramming  can  be  obtained. 

No  extra  compensation  shall  be  paid  to  the  Contractor  for 
the  use  of  such  concrete,  the  cost  of  which  is  to  be  included  in 
the  price  herein  stipulated  for  the  masonry  in  connection 
with  which  it  is  used. 

The  faces  of  the  all  masonry  dam  (  Plan  A  )  shall  be  built  of 
rubble  masonry  laid,  in  general,  in  the  same  manner  as  the  cen- 
tral portion,  so  as  to  produce,  as  far  as  possible,  a  homogene- 
ous mass.  The  soundest  and  best  shaped  stones  shall,  how- 
ever, be  selected  for  this  work  and  shall  be  laid  in  such  a  manner 
as  to  break  joints  and  make  the  best  possible  face.  All  joints 
for  a  depth  of  two  inches  shall,  if  necessary,  be  raked  out  clean 
and  shall  then  be  carefully  pointed  with  Portland  cement  mortar, 
mixed  with  sharp  sand  in  the  proportion  of  one  part  of 
cement  to  two  parts  of  sand.  Great  care  shall  be  taken,  espe- 
cially in  the  up-stream  face,  to  produce  a  face  impervious  to 
the  passage  of  water. 

The  cost  of  this  face  stone  and  of  the  pointing  shall  be 
included  in  the  cost  of  dam  masonry,  as  hereinafter  stated, 
(Clause  Q,  item  f). 

Concrete  masonry  will  be  used  in  the  all  masonry  dam 
(Plan  A)  to  fill  up  irregularities  in  the  bedrock  foundation 
and  in  joining  the  masonry  to  the  rock  at  the  ends  of  the  dam 
and  also,  at  the  option  or  with  the  approval  of  the  Engineer, 
in  place  of  mortar  and  spalls  in  the  heart  of  the  dam.  For 
joining  the  foundation  to  the  bedrock  and  in  such  other  places 
as  he  may  deem  proper,  the  Engineer  may.  at  his  discretion, 
order  the  use  of  neat  cement,  in  place  of  concrete  or  mortar. 
This  shall  be  paid  for  per  barrel  of  four  hundred  pounds  at  the 
price  hereinafter  stated.  (Clause  Q,  items  h  and  j). 

Concrete  masonry  in  Plans  B  and  C  will  be  used  in  all 
parts  of  the  structure,  excepting  the  coping  of  the  dam,  the 
Plans  B&C  crest  and  steps  of  the  waste  weir,  where  cut  dimension  stone 
may  be  used,  wherever  ordered  by  the  Engineer. 

All  concrete  shall  be  made  of  Portland  cement,  sand  and 
broken  stone,  of  the  quality  hereinafter  specified.  There  shall 
be  two  grades  of  concrete,  paid  for  at  different  prices  (Clause 
Q,  items  f  and  g).  The  proportions  of  the  mixture  by  volume

be,  one  part  of  cement  to  two  of  sand  and  four  parts  of 
broken  stone  in  the  richer  grade;  and  one  part  of  cement,  to 
three  parts  of  sand  and  five  parts  of  broken  stone  in  the  poorer 
grade.  The  grade  of  cement  to  be  used  in  any  given  part  of 
the  work  will  be  determined  by  the  Engineer.  In  computing 
the  amount  of  cement  used  in  a  given  mixture,  it  shall  be 
measured  as  packed  in  barrels,  the  cubic  contents  of  a  standard 
barrel  of  Portland  cement  weighing  four  hundred  pounds  being 
taken  as  equal  to  one-eighth  of  a  cubic  yard. 

The  volume  of  the  sand  and  broken  stone  shall  be  meas- 
ured when  loose!  v  packed  in  boxes  or  barrows  of  any  conven- 
ient standard  size. 

A  stronger  mixture  will  be  used  in  some  parts  and  a 
weaker  mixture  in  others,  the  average  amount  of  cement  used 
to  be,  as  nearly  as  may  be,  as  above  stated. 

In  the  lower  and  thicker  portions  of  the  piers  and  abut- 
ments, the  Contractor  will  also  be  j>ermitted  to  embed  in  the 
concrete  a  considerable  portion  of  larger  stones,  not  to  exceed 
about  ten  cubic  feet  in  volume.  These  stones  shall  be  of  proper 
shapes,  they  shall  be  thoroughly  wet  before  being  used  and 
shall  be  so  laid  as  to  be  entirely  enclosed  by  concrete  on  all 
their  surfaces.  There  shall  be  at  least  twelve  inches  of  con- 
crete between  any  two  adjacent  stones.  The  proportion  of 
stones  to  be  embedded  and  their  size  and  shape  shall  be  at  all 
times  subject  to  the  approval  of  the  Engineer. 

The  method  of  making  all  concrete  shall  be  the  following: 
The  sand  and  cement  shall  first  be  properly  mixed  together 
dry,  then  formed  into  mortar  by  adding  a  proper  dose  of  clean 
water   and    again    thoroughly    mixed,     whereupon    the   ballast, 
properly  moistened,  shall    be  quickly    added    and    mixed    with 
the  mortar,  either  in  an  approved  machine,  or  by  rapidly  turn- 
ing over  the  mass  with  the  proper  tools  upon    a   suitable  plat- 
form twice  or  more  times,  as  the  Engineer  may   direct.       The 
resulting  concrete  shall  be  free  from  surplus   water,    but   thor- 
oughly moistened  throughout,    and   the   voids   between   stones 
shall  be  completely  filled    with  mortar  in  excess.       As   soon  as 
the  mixing  is  completed,  the  concrete  must  be  deposited  rapidly 
Admixture    in  the  place  where  it  is  required  and  thoroughly  rammed  and 
with  Mortar  pOU1K]e(]7    jn    a    manner    satisfactory    to  the   Engineer,   until 
th»  water  flushes  to  the  surface  and  all  the  spaces  are  entirely

filled  with  morta''.  Should  voids  afterwards  be  discovered,  the 
defective  work  is  to  be  removed  and  the  spaces  refilled  with 
suitable  material  at  the  Contractor's  expense  Any  concrete 
mixed  aud  left  standing  so  as  to  take  an  initial  set  shall  not  be 
used  in  the  work.  In  no  case  shall  mortar  or  concrete  that  has 
been  left  standing  over  night  be  used.  Care  must  be  taken 
against  too  severe  or  long  continued  pounding,  thereby  forcing 
the  broken  stone  to  the  bottom  of  the  layer,  or  disturbing  the 
incipient  set  of  concrete.  In  all  cases,  the  concrete  must  be  al- 
lowed to  set  for  a  sufficient  time  after  being  deposited  in  place, 
before  walking  over  or  working  upon  its  surface  is  permitted. 
The  time  thus  required  shall  be  determined  by  the  Engineer. 

In  case  it  is  necessary  to  lay  concrete  in  water,  the  mate- 
rial shall  not  fall  from  any  height,  but  shall  be  deposited  in  a 
compact  mass  in  the  allotted  place  by  the  use  of  such  appli- 
ances as  will  be  approved  by  the  Engineer. 

In  building  the  concrete  piers  and  arches  ( Plans  B  and  C) 
great  care  shall  be  taken  to  obtain  a  thoroughly  sound  and  uni- 
form grade  of  concrete  in  each  part  of  the  work.  The  molds 
shall  be  securely  and  strongly  built  of  plank  at  least  two  inches 
in  thickness  and  they  must  be  thoroughly  secured  in  every  di- 
rection by  bracing,  so  as  to  insure  the  correct  shape  aud  posi- 
tion of  the  concrete  work.  The  plank  used  shall  be  tongued 
and  grooved,  with  a  smooth  surface  on  the  inner  side  of  the 
mold,  and  tightly  fitted  together,  so  as  to  leave  very  small 
joints  aud  as  finished  a  surface  as  possible. 

If  necessary,  to  prevent  adhesion,  the  inner  surfaces  of 
the  molds  shall  be  painted  with  a  thin  coat  of  crude  black  oil. 

The  outer  surfaces  of  the  concrete  work  must  be  smooth 
and  perfect,  showing  as  few  large  stones  and  marks  of  the 
mold  as  possible. 

Plastering  of  the  finished  wall  will  not  be  required  unless 
the  above  result  should  not  be  obtained  during  the  filling  of 
the  molds.  To  insure  this,  a  portion  of  the  mortar  used  in 
making  each  batch  of  concrete  shall  be  retained  and  used, 
without  the  addition  of  broken  stone,  for  those  portions  of  the 
work  nearest  the  face.  In  doing  this,  the  mortar  shall  be  piled 
up  for  each  layer  in  a  triangular  heap  close  to  the  molds,  thus 
making  a  bond  with  the  central  portion  of  the  work.  After  the 
molds  are  filled,  they  shall  not  be  removed  for  at  least  three 


35 

days,  or  longer  if  necessary,  and  the  concrete  shall  be  sprinkled 
and  kept  wet,  as  long  as  may  be  deemed  necessary  by  the  En- 
gineer, to  prevent  cracking. 

The  broken  stone  for  concrete   shall   consist  of  fragments 
of  durable  stone,  broken   so   as  to   measure   no   more  than  two 
inches  in  any  direction.      All  this  material  shall  be  free  from 
Broken         dust,  dirt,  clay,  or    other    improper  substance  and,  when  re- 
Stone,          quired  by  the  Engineer,  it  shall  be  washed  before  being  mixed 
with  cement   mortar.      Any    material   under   J   of  an    inch   in 
diameter,  unless  required  by  the  Engineer  to  be  screened  out, 
shall  be  counted  as  so  much  additional  sand  and  the  volume  of 
sand  reduced  proportionately. 

Sand  shall  be  clean,  coarse,  and  silicious;  it  must  be 
screened  and  washed,  if  required  by  the  Engineer,  and  must 
be  subject  to  his  approval  as  to  fineness  and  other  qualities. 


CEMENT. 

In.  the  construction  of  the  dam  and  in  all  other  wyork  con- 
nected with  it,  Portland  cement  is  to  be  used,  which  must  be 
of  a  superior  quality.  It  shall  be  well  packed  in  strong  bar- 
rels of  standard  size,  so  as  to  be  reasonably  secure  from  air. 

Vigorous  and  continuous  tests  will  be  made  of  all  cements 
to  be  used.  Samples  may  be  taken  from  each  and  every  barrel 
and  a  failure  of  one-tenth  of  the  samples  tested  ruav  be  suf- 
ficient cause  for  the  rejection  of  all  barrels  in  the  same  lot  from 
which  the  samples  have  been  taken.

Tests.  strength  of  standard  briquettes  of  i/m/  cement,  one  inch  square 

at  their  least  section. 

All  cement  to  be  accepted  must  conform  to  both  of  the 
following  tests: 

When  left  one  hour  in  the  air  and  the  balance  of  24  hours 
in  water  of  a  temperature  of  about  60  degrees,  the  briquette 
shall  stand  a  tensile  stress  of  at  least  100  Ibs.  per  sq.  in.  before 
breaking.  When  left  24  hours  in  the  air  and  six  days  in  water 
of  a  temperature  of  about  (iO  degrees,  the  briquette  shall  stand 
a  tensile  stress  of  at  least  300  Ibs  per  sq.  in. 


86 

The  degree  of  fineness  shall  be  such  that  at  least  85  per 
cent,  shall  pass  through  a  standard  No.  100  sieve,  (10,000 
meshes  to  the  square  inch).  A  cement  that  cracks  or  checks 
when  made  into  thin  cakes,  or  that  begins  to  set  in  less  than 
twenty  minutes,  shall  not  be  accepted. 

It  must  also  test  and  act  to  the  satisfaction  of  the  Engi- 
neer when  mixed  with  sand,  and  will  be  subject  to  constant  in- 
spection. If  other  than  the  tensile,  tests  ordinarily  made  seem 
necessary  to  the  Engineer,  he  shall  have  the  privilege  of  con- 
ducting the  same  and,  if  the  cement  fails  to  pass  any  of  them 
to  his  satisfaction,  it  shall  be  rejected.  No  charge  shall  be 
made  for  samples  of  cement  taken  for  such  tests.  The  Con- 
tractor shall  at  all  times  keep  in  store,  at  some  convenient 
Cement  point  in  tha  vicinity  of  the  work,  a  sufficient  quantity  of  ce- 
ment to  allow  ample  time  for  the  tests  to  be  made,  without  de- 
lay in  the  work  of  construction.  It  shall  also  be  stored  in  a 
tight  building  and  each  cask  must  be  raised  above  the  ground 
bv  blocking,  or  otherwise.  As  soon  as  notified  of  the  arrival 
of  the  cement,  the  Engineer  will  cause  to  be  made  such  tests 
as,  in  his  judgment,  may  be  uecessarv.  If  any  cement  is  found 
of  improper  quality,  it  shall  be  branded,  and  must  be  imme- 
diately removed  from  the  work. 

PLANS  B  AND  C. 

STEEL. 

The  treatment  and   manufacture   of   the   steel   plates   and 
Steel  Plat  s  r*ve*s  used  in  the  facing  of  this  form  of  dam   shall  conform  in 
andRivets.  all  respects  to  the  following  requirements    and  to   the    detailed 
drawings  to  be  furnished  for  this  work. 

REQUIREMENTS  FOR  STEEL  PLATES  AND  RIVETS. 

The  steel  shall  be  of  the  class  termed  "soft  medium''  and 
shall  be  made  by  the  open  hearth  process,  either  the  basic  pro- 
cess or  the  acid  process,  as  the  Engineer  may  determine.  If 
made  oy  the  basic  process,  the  percentage  of  phosphorus  shall 
not  exceed  .04  and  of  sulphur  not  be  greater  than  .04:  if  made 
by  the  acid  process,  it  shall  not  contain  more  than  .07  per  cent, 
of  phosphorus  and  not  more  than  .04  of  sulphur.  The  per- 
centage of  manganese  shall  not  be  greater  than  .60  per  cent. 
Each  sheet  shall  be  uniformly  homogeneous  in  quality,  and 


Chemical 
Analyses. 


Physical 
Tests. 


should  n  reasonable  doubt  exist  as  to  the  quality  or  uniformity 
of  the  steel  furnished,  the  Engineer  may  order  additional  tests 
before  acceptance. 

A  sufficient  number  of  chemical  analyses  of  each  heat  or 
melt,  to  determine  the  quality  of  the  steel,  shall  be  made  by 
the  manufacturer  without  expense  to  the  Company,  and  proper- 
ly certified  copies  of  the  final  analyses  of  the  finished  material, 
giving  percentages  of  carbon,  phosphorus,  manganese  and 
sulphur,  sliall  be  furnished  to  the  Engineer  of  the  Power  Com- 
pany, or  his  representative,  as  the  work  progresses. 

Physical  tests  to  determine  the  tensile  strength,  elastic 
limit,  softness  and  ductility  of  the  material  of  each  heat  or 
melt  shall  also  be  made  at  the  expense  of  the  Contractor  by  an 
experienced  Inspector,  whose  services  shall  be  satisfactory  to 
the  Chief  Engineer  of  The  Pioneer  Electric  Power  Company, 
and  who  shall  keep  a  complete  record  of  all  analyses  and  tests 
identifying  each  by  its  respective  melt  number.  Such  record 
shall  be  open  to  inspection  of  the  Engineer  at  any  and  all 
times. 

For  the  purpose  of  identification,  the  heats  or  melts  shall 
be  numbered  consecutively  and  the  corresponding  number 
stamped  upon  each  plate  or  sheet  produced  therefrom.  A  lack 
of  sufficient  identification  may  be  cause  for  rejection  of  an  en- 
tire heat  or  melt. 

Test  pieces  shall  be  furnished  from  at  least  twenty  per- 
cent, of  the  finished  material  of  each  melt,  but  at  least  two  test 
pieces  shall  be  made  from  every  melt.  The  plates  or  sheets 
Furnished,  from  which  test  pieces  are  taken  shall  be  selected  at  random 
by  the  Inspector,  and  each  piece  shall  be  numbered  with  the 
corresponding  melt  number. 

Tensile  test  pieces  shall  be  at  least  sixteen  inches  long  and 
shall  have,  for  a  length  of  eight  inches,  a  uniform  planed  edge 
.    sectional  area  of  at  least  one-half  square  inch,  the  width  in  no 
case  to  be  less  than  the  thickness  of  the  piece. 

Bending  test  pieces  to  be  twelve  inches  long  and  to  have  a 
width  not  less  than  four  times  the  thickness,  with  edges  planed 
smooth.

Drifting  test  pieces  shall  be  three  inches  wide  and  not  less 
than  five  inches  long. 

Test  pieces  as  above  shall  give  results  as  follows:  Ulti- 
mate strength,  55,000  pounds  to  65,000  pounds.  Elastic  limit, 
not  less  than  one-half  ultimate  strength.  Elongation,  not  less 
than  24  per  cent,  in  eight  inches.  Reduction  of  area  at  frac- 
ture, at  least  48  per  cent. 

All  fractures  shall  be  fine,  silky  and  free  from  crystalline 
appearance,  or  from  indications  of  injurious  treatment  or  in- 
sufficient working. 

Bending  test  pieces  shall  bend  double  under  the  hammer, 
cold,  without  signs  of  cracking. 

In  punching  test  pieces,  a  row  of  eight  holes.  £  of  an  inch 
in  diameter  and  1^  inches  between  centers  shall  be  punched 
without  any  cracks. 

In  drifting  test  pieces,  not  less  than  two  holes,  ^  of  an 
inch  in  diameter,  spaced  two  inches  between  centers,  shall  be 
punched  and  then  enlarged  by  blows  from  a  sledge  hammer 
upon  a  di  if  ting  pin  until  said  holes  are  1^  inches  in  diameter, 
without  showing  signs  of  failure  or  cracking  on  the  inside  of 
the  hole  or  edge  of  the  plate.  Punching  and  drifting  tests  to 
be  made  cold. 

The  plates  must  also  admit  of  cold  hammering  or  scarfing 
to  a  fine  edge  at  the  laps  without  cracking,  and  the  test  pieces 
must  furthermore  withstand  such  quenching,  forging  and  other 
rests  as  may  satisfy  the  Inspector  as  to  the  temper,  soundness 
and  fitness  for  use  of  the  material. 


Any  failure  of  test  pieces,  taken    at    random    as   aforesaid, 

Failure  of    to  conform  to  the  above  requirements  may.  at  the  discretion  of 

Test  Pieces  the  Engineer  or  Inspector,  cause   the   rejection  of   the  entire 

product  of  the  heat  or  melt  from  which   such    pieces  are  taken. 

All  finished  material  shall  be  free  from  laminations,  cracks, 
blisters,  scale  or  cinder  sjx)ts.  and  have  clean  edges   and   good 
surface  free  from  bends.     The  plates  shall  be  fully   up  to  the 
required  thickness  at  all  points.       Any   plate    whose   thickness 
of  Plates,      at  any  point  may  be  found  less  than  the  required  thickness   by- 
more  than  1-100  of  an  inch  shall   be    rejected   without   appeal. 
Plates  varying  more  than  five  per  cent,  from    the   weights   per

The  Engineer  of  the  Power  Company,   or   his    representa- 
tive, shall  have  the  right  at  all  times  to  inspect  the    process  of

It  is  understood  and  agreed  that  any  plate  that  shows  any 
defect  during  the  process  of  punching,  bending,  or  riveting 
shall  be  rejected,  notwithstanding  that  Ihe  same  may  previous- 
ly have 'been  satisfactorily  tested. 

Rivets  shall  be  made  of  a  good  grade  of  soft  steel  and 
shall  have  a  tensile  strength  between  the  limits  of  56,000

order  the  Contractor  to  increase  their  efficiency  or  to  improve 
their  character,  and  the  Contractor  must  conform  to  such  or-

of  the  work  as  will  give  reasonable  grounds  for  anticipating 
its  completion  within  the  required  time,  the  Company  shall 
have  power  to  notify  the  Contractor  to  discontinue  all  work,  or 
any  part  thereof,  under  this  contract;  and  thereupon  the  said 
Contractor  shall  cease  to  continue  said  work,  or  such  part 
thereof  as  the  Engineer  may  designate;  and  the  said  Company

of  the  work  left  uncompleted  by  the  Contractor,  or  for  the  cor- 
rection of  the  whole  or  any  part  of  said  work.  And,  in  case 
the  expense  so  incurred  by  the  Company  is  less  than  the  sum 
which  would  have  been  payable  under  this  contract  if  the  same 
had  been  completed  by  the  Contractor,  then  the  Contractor 
shall  be  entitled  to  receive  the  difference;  and  in  case  such  ex

rectly or  indirectly ;  provided,  that  notice  in  writing  of  such 
claims,  signed  by  the  claimants,  shall  have  been  previously 
filed  in  the  office  of  the  Engineer. 

The  said  Contractor  further  agrees  that  he  will  indemnifv
